【问题讨论】：

标签： node.js heroku webpack

【解决方案1】：

您的package.json 中缺少express。此外，webpack 和 webpack-dev-server 是 devDependencies，Heroku 可能没有安装。

运行

npm i --save express webpack webpack-dev-server

然后提交并推送您的package.json 和package-lock.json 并重新部署。

如果webpack和webpack-dev-server不在dependencies下，而是devDependencies在package.json下运行，运行npm uninstall webpack webpack-dev-server，然后再次运行命令。

【讨论】：

感谢您的帮助。我必须删除一些 .bin 文件才能卸载并安装它。我得到这个 TypeError: webpack.NoErrorsPlugin is not a constructor.
